Application filed February 2, 1916. Serial No. 75,720.

.To all whom t may concern:

Be it known that I, Louis J. ScHn'r'rL, a citizen of the United States,residing at liffanitowoc, in the county of Manitowoc and State of`Wisconsin, have invented certain new and useful Improvements inHydrocarbon-Burners, of which the following is a specification.

This invention relates to hydrocarbon burners, and has particularreference to a burner for oil or other hydrocarbon fuel in which the oilis vaporized and mixed with sufficient quantity of air to supportcombustion and burn the gas.

The invention provides a burner which will generate steam to be used formixing with the hydrocarbon to produce a gaseous fuel which will burnwith a clear flame and be free from carbon.

The invention further consists in the provision of a burner head, fueland water supply tanks, and pipe lines connecting the tanks with thehead, the pipe lines from each of the tanks having coils formed thereinand arranged in advance of the burner head so that the jet of flameissuing` from the head will heat the coils and vaporize the fuel andwater therein so that the fuel will be sup plied to the head in a highlyvolatile state and also the water in the form of steam. Compressed airis supplied to the tanks for feeding the fuel and water to the burnerfrom any desired source, and it is another object of the invention toprovide means whereby the pipe lines between the tanks and burner headmay be cleaned by the use of such air.

A further object of the invention is t0 provide a novel and efficientform of burner ti PA still further object of the invention is to providea burner of this character which is extremely simple in construction,cheap and easy to manufacture, and which is thoroughly reliable andefficient in operation.

With the foregoing and other objects` in view, the invention consists inthe novel features of construction, combination and arrangement ofparts, as will be hereinafter, more fully described, illustrated in theaccompanying drawings, and claimed.

1n the drawings Figure 1 is a side elevation of the complete burner.Fig. 2 is a top plan. Fig. 3 is a detail longitudinal section throughthe burner head. Figyll is a detail section through the burner tip; andFig. t5. is a plan of one of the plugs of the burner Referring to thedrawings by numerals, wherein is illustrated the preferred embodiment ofmy invention, 1 designates a suitable supporting structure which hassup` ported thereon in any suitable manner, as by the brackets 2, oiland water tanks 3 and l, respectively, the said tanks being of anydesired capacity and being arranged adjacent each other in spacedrelation. Each of these tanks is provided with a filling opening at itsupper end, which is closed by a cap 5, while the water tank 4: isprovided at its lower end with a drain pipe 6 which may be provided witha suitable valve to permit the draining of this tank.

Gages 7 and 8 are arranged upon the oil and water tanks respectively,and are of the usual construction. From the lower end of the gage 8extends a pipe 9 which has arranged therein a T-fitting 10. This pipe 9then extends upwardly and is connected with a pipe line 11 carried bythe burner head, indicated in its entirety at 12.

The burner head 12 comprises a cylindrical tube 13 of any desired sizeand which is preferably closed at its rear end. Within the tube 13 nearits front end and extending diametrically across the same is a hollowmember 15, preferably cylindrical in shape and having a central diaphraml5L dividing it into two chambers 14 and lta. The ends of the member 15each have an opening therethrough communicating with one of the interiorchambers as illustrated in Fig. 4. Openings 13a and 13b similar to theopenings in the member 15 are formed in the sides of the tube 13 andcoincident therewith for a purpose to be described later. The member 15is provided on its forward side with two projecting nipples 16, thebores 17 of which communicate respectively with the chambers 14 and 141aand incline toward each other. Short tubes 18 are threaded in the bores17 and at their outer converging ends carry caps 19. Each of the caps 19is preferably threaded upon the outer end of a tube 18 and is providedwith an internally threaded bore to receive plugs 20. These plugs areprovided with any desired number of radially extending slots 21 whichare preferably arranged diagonally of the longitudinal extent of theplugs so that gas or fluid issuing Cpt therethrough from the tubes 18will be given a rotary or twisting motion, as will be understood. v

The pipe 11 extends longitudinally along the outer face of the tube 13and is supported thereon by means of brackets This pipe extends beyondthe open end of the Y rearwardly, as at 24, and is threaded in theVopening 13b in the tube 13y and into one of the end openings of themember 15. A needle valve 25 is arranged in the pipe line 11 between thecoil 23 and tank el. in order to adjust and vary the supply of water tothe coil23. Y

A' pipe 26 is connected at one'end with the fitting 10 and at itsonpositeend with a four-way fitting 27. `This pipe is arranged parallelto the tanks, and intermediate its ends is provided with a. T-fitting 28to which is comiected one end of apipe 29, its opposite end-beingconnected with an air compressor of any suitable type. The fitting 27 Yis further provided with a short pipe 30 upon which is arranged apressure gage 31. Pipes 32 and 33 also connect the fitting 27 with thetanks 3 and it respectively, a valve 3J: being arranged in the pipe 32as is clearly illustrated in F ig. 1 of the drawings.

The pipe line 9 is provided wit-h a valve 35 arranged therein betweenthe fitting 10 and the gage 8, while the pipe 2G is provided 'with avalve 36' arranged therein between the fittings 10 and 28.

Communicating with the lower end of the gage 7 of the oil tank is a pipe37 which extends upwardly from the gage and communicates with a pipe 38arranged longitudinally of and supported by the tube 13 by means ofbrackets 39. This pipe is arranged upon the opposite face of the tube 13from the pipe11 and is extended forwardly of the open end of the tubewhere it is formed into a coil Ll0. Thiscoil 40 extends at substantiallyrightV angles to thefpipe 38 and is arranged in advance of the open endof the tube and between such open end and the coil The opposite end ofthis coil is extended rearwardly, as at 41, and is threaded into theopening 13 upon the opposite face of the tube 13 to that with which thepipe 24; is engaged. VThis pipe L11 communicates with the adjacentthreaded endof the member 15. i needle valve 42 is arranged in the pipeline 38 between the coil and the gage and is adapted to Vbe adjusted toVvary the supply of oil to the burner head, while asecond valve 43 isarranged within this pipe line whichis adapted to be operated to open or'entirely cut off the supply of fuel from the f tank 'to' the burner.

amount of air to the tube to mix with the fuel issuing from the burnertip to support combustion and provide for the proper burning of thefuel.

In operation, the valves and i3, in the pipe lines 9 and 37,respectively, are opened and the needle valves 25 and .42 adjusted topermit of the proper quantity and proportion of water and oil beingadmitted to thel coils 23 and 40 respectively, air under pressure fromthe compressor having first been supplied to the tanks to cause thewater and oil to be forced through the pipe lines. Au initial lightingof the fuel at the burner tip is accomplished in any desired manner andthe jet. of fiame issuing therefrom will heat the coils and cause t-heoil and water therein to be heated and become vaporized, where.- uponthe pressure created in the coils by such vaporization will cause thegas and` steam thus formed to pass to the respective chambers 1land 14Cof the member 15 and out through the tubes 18 and diagonally extendingslots 21, which latter tend to givrthe flame a rotary motion. Asufiicient amount of air is drawn through the openings elel. in the tube13 to support proper combustion at the burner tip.

From the foregoing it is thought that thi` construction and operation ofthe improved burner will be clearly understood.

I have so arranged the several pipe lines and the valves therein thatthe water tank may be drained as well as the water suppl): pipes toprevent bursting of the tank or pipes in cold weather. By first openingthe valve in the drain pipe G, the contents of the tank may be drawnoff. However, thisy draining of the tank will not drain the water fromthe water pipes and therefore, I hav(` so arranged the several valvesthat air under pressure from the air compressor ma \v be utilized forcleaning these pipes out. After the water has been drained from the tankthe valve in the drain pipe 6 is closed.

as is the valve 3ft in the pipe 32. This causes air from the aircompressor to travel to the tank, valve 36 in the pipe 26 having firstbeen closed and the valve 35 opened so that such air will travel outthrough the gage 3. through the pipes 9 and 11, coil 23, pipe 2i. andout through the burner tip which will force allwater and foreign matterfrom the pipes. If it is desired to clean the pipes merely withoutdrawing off the contents of the tank, the valve 35 may be closed and thevalve 86 opened whereupon the air will travel downwardly though the pipe26 and thence through the pipes 9 and 11, coil 23, pipes 24- and throughthe burner tip.

F rom the foregoing description taken in connection with theaccompanying drawings, it is thought that the construction and operationof my improved burner will be readily understood and while I have hereinshown and described one preferred embodiment of my invention, I do notwish to be limited thereto except for such limitations as the claims mayimport.
